你不用配置文件当然可以发布了，你在创建ServiceHost的时候已经传入了base address，这时就不会再使用配置文件中的值了。

你好，是不是用IE打开地址找不到任何信息，你得公开元素据，配置如下

  <services>
      <service name="Microsoft.ServiceModel.Samples.CalculatorService" behaviorConfiguration="CalculatorServiceBehavior">
        <endpoint address="http://localhost:8000/ServiceModelSamples/service" binding="wsHttpBinding" bindingConfiguration="" contract="Microsoft.ServiceModel.Samples.ICalculator"/>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="CalculatorServiceBehavior">
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>

用代码实现如下

ServiceMetadataBehavior metabehavior = new ServiceMetadataBehavior();
ServiceBehaviorAttribute behaviorAttribute = new ServiceBehaviorAttribute();
behaviorAttribute.IncludeExceptionDetailInFaults = true;
metabehavior.HttpGetEnabled = true;

host.Description.Behaviors.Add(metabehavior);

这样你就可以访问到服务了
